standard dosing schedule is 2.5 for 4 weeks, 5 for 4, 7.5 for 4, 10 for 4, 12.5 for 4, then 15 until goal. some people respond fast and stay low. i never went above 10 until the last 10 pounds, then 15 for a month. took 18 months total to drop 90.
The steady state approach - going in at lower doses to let levels accumulate gradually - is exactly right for avoiding the worst of the sides. The assumption that smaller peaks are less likely to cross the symptom threshold holds up in practice for most people.
Staying at the dose that's working and not pushing higher just because higher doses exist is exactly the right logic. The purpose of titration is to find your effective level, not to maximize the dose. Staying at 7.5mg indefinitely is the definition of a successful outcome when it's holding your results.
